Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for coating the surface of a can, in which the surface of the can is coated to give the appearance of water droplets or frost.

(Prior Art) Canned beverages are often very delicious when cooled.

Therefore, when canned beverages are chilled well, water droplets and frost often form on the surface of the can, which gives the impression that the drink is well-chilled, which stimulates the desire to drink.

On the other hand, canned beverages are sold in large numbers through vending machines and the like, and there are many types of them.

Therefore, sales can be greatly influenced by the quality of the product samples displayed at the top of the vending machine. Therefore, when creating product samples, we take the best possible measures to make them look as delicious as possible.

To this end, conventional methods have been to make the printing as clear as possible, to improve the lighting, and to make other improvements to the display.

(Problems to be Solved by the Invention) However, with the above-mentioned devices, there is only the presence of the product itself, and it does not particularly arouse the desire to drink.

Therefore, there is a problem in that there is not much difference between the products and other displayed products, and the reality is that the product is influenced by the popularity of the product itself.

Therefore, in view of the above-mentioned problems, this invention was created with the aim of making it possible to paint the surface of a can so that the user's desire to drink can be aroused just by looking at the product samples on display. be.

(Means for Solving the Problems) This invention involves applying a silicone-based transparent paint to the surface of the can, applying an undercoat and curing it, and then applying the above-mentioned paint on top of the undercoat so that it forms water droplets. The above-mentioned problems can be solved by spraying a similar paint a suitable number of times and curing it as it is, and in particular by using an ultraviolet curable paint as the silicone-based transparent paint.

(Function) The method of painting the can surface according to the present invention is to apply a silicone-based transparent paint to the can surface, apply an undercoat and cure it, and then apply the above paint on top of the undercoat so that it forms water droplets. Spray the same paint an appropriate number of times.

In this case, the silicone-based paints have the property of repelling each other because the undercoat is hardened, and by allowing it to harden as it is, it hardens and is painted in the form of water droplets.

At this time, the most suitable coating is an ultraviolet-curable silicone-based transparent coating, which cures simply by irradiating it with ultraviolet light and leaves water droplets as they are without the need for heating.

(Example) The present invention will be described in detail below with reference to the drawings.

That is, the reference numeral 1 shown in the figure is a display can, and although not shown, decorative patterns, designs, characters, etc. are appropriately printed on the surface of the can.

First, as shown in (B), this display can 1 shown in (A) is coated with a silicone-based transparent paint 3 by spraying it over the entire surface using a paint spraying device 2. After this paint 3 is cured, as shown in (C), the same paint 3 as the above-mentioned paint is again sprayed a suitable number of times to apply the paint in the form of water droplets on the surface of the display can 1. The grains 4 are left behind and hardened.

In this case, it is optimal to use an ultraviolet curing type paint as the paint 3.

Specific examples of these steps are shown below.

The following specific examples are carried out by sequentially performing three steps: undercoating, intermediate coating, and topcoating.

First Example Undercoat paint name: ll05800tl ultraviolet curable paint (manufactured by Fujikura Kasei) Coating amount: 1.1 tag/cd Injection pressure 4kg/cst Spraying distance: 15cm Irradiation conditions: 4 lamp irradiation (1, J?, 70℃) Intermediate coating paint name: HO5800jl ultraviolet curable paint (manufactured by Fujikura Kasei) Coating amount: 1.1 mg/cd Injection pressure 4kg/cd Injection distance: 15cm Irradiation conditions = 4 lamp irradiation (f, I?, none) ) Apply so that paint particles 4 are small particles.

Top coat name: υR4201 UV curable paint (manufactured by Mitsubishi Rayon) Coating amount: 5.5■/cj Injection pressure: 0.1 dazzle/cd Spray distance H: 10cm Irradiation conditions 2: Lamp irradiation (1,1? , None) Paint particles, 4, apply so that they are large particles.

As a result, large paint particles 4 were formed on the small particles, giving an appearance similar to that of water droplets that had been cooled to an appropriate temperature.

Second Example Undercoat paint name: HO5800tl ultraviolet curable paint (manufactured by Fujikura Kasei) Coating amount: 1.1 mg/cj Injection pressure 4 kg/cd Injection distance: 15 cm Irradiation conditions = 4 lamp irradiation (+, R, 70℃) Intermediate coating paint name: HO5800U ultraviolet curable paint (manufactured by Fujikura Kasei) Coating amount: 3.3 mg/c injection pressure 0.1 kg/cj injection distance: lOc+n Irradiation conditions: 4 lamp irradiation (+, L None) Apply so that paint particles 4 are large.

Top coat name: UR4201 UV curable paint (manufactured by Mitsubishi Rayon) Coating amount: 1.1 mg/c injection pressure 3 kg/cj injection distance: 15 cm Irradiation conditions 2: Lamp irradiation (1, R, none) paint grain 4
Apply so that it becomes small particles.

As a result, small paint particles 4 were formed on the large particles, giving an appearance similar to that of water droplets that had been cooled to an appropriate temperature.

3rd Example Primer paint name: HO5800U ultraviolet curable paint (manufactured by Fujikura Kasei) and TR matte material (manufactured by Toho Kaken) were mixed in a ratio of 3=1. 5.6mg/c injection pressure H3kg10II injection distance: 2Gcm Irradiation conditions: 4 lamp irradiation (+, R, 70℃) Intermediate coating paint name: HO580011 ultraviolet curing paint (manufactured by Fujikura Kasei) Coating amount: 1.1ag/( 4 Injection pressure crab 3kg/cJ Injection distance: 20cm Irradiation conditions: 4 lamp irradiation (+, R, none) Paint particles 4
Apply a thick coating so that it becomes small particles.

Top coat name: UR420L UV curable paint (manufactured by Mitsubishi Rayon) Coating amount: 5.5 mg/cj Injection pressure: 0.1 kg/cj Spray distance: 10 cm Irradiation conditions = 6 lamp irradiation (+, R, none) Paint grain 4
Apply so that it becomes large particles.

As a result, small and even larger paint particles 4 are formed on the surface that has been covered with fine frost, giving an appearance similar to that of a surface that has been cooled to a considerably low temperature. Ta.

In addition to the above-mentioned 1105800υ ultraviolet curing paint, HO5123U, +105825 ultraviolet curing paint (both manufactured by Fujikura Kasei) etc. can also be used as paints.
The application amount is 0.7mg/c ~ 6.5cm/cd
, injection pressure is 0.05 kg/c ~ 6.5 kg/c
It is sufficient to do so within the range of It goes without saying that even if it exceeds this range, any range may be used as long as it can be coated in the state described above.

(Effects of the Invention) In the present invention configured as described above, a silicone-based transparent paint 3 is applied to the surface of the can 1, an undercoat is applied and cured, and then the above-mentioned paint is applied on top of the undercoat so as to form water droplets as appropriate. By spraying the paint 3 an appropriate number of times and letting it harden as it is, the silicone paint 3 has the property of repelling each other because the undercoat is hardened, so by letting it harden as it is, it will harden as it is in the form of water droplets. It will be painted.

Therefore, the cured transparent paint 3 remains in the form of water droplets.
In appearance, it looks as if water droplets have adhered to the surface of the can 1. Therefore, the beverage in the can 1 appears to be cooled to an appropriate temperature, which arouses the beverage's desire to drink.

At that time, the most suitable silicone-based transparent paint 3 is
It is an ultraviolet curable paint that cures simply by irradiating it with ultraviolet light, leaving water droplets as they are without the need for heating.

As a result, cans 1 for display in vending machines, etc. are generally kept in display cases and are not touched directly with hands, etc., so if such cans 1 are coated with the above coating, The display can 1 itself appears to be cooled, which arouses the desire to purchase.

The can surface coating method according to the present invention may be applied not only to the display can 1 but also to actual beverage cans, and even if it has other configurations, it is not limited to the above-mentioned embodiments. Needless to say, there is no such thing.

In this way, according to this invention, since it looks like water droplets or frost are attached to the surface, it creates an image that it is very well cooled, and just looking at the product samples on display increases the desire to drink. It has various excellent effects such as stimulating the mood.
